The theory of " heart governing the exterior" derives from Prohibition of Pricking in Suwen, which has an important position in the clinical practice of traditional Chinese medicine. This article sorts out the interpretation of " heart governing the exterior" of physicians in the past dynasties, and summarizes the clinical application of " heart governing the exterior" in chest painful impediment, warm disease, dermatosis, allergic rhinitis, tic disorder, and diabetic neuropathy. It is found that the theory of " heart governing the exterior" is widely used in clinical practice and has good effects. This paper further expands and enhances its theoretical connotation, that is, the physiological and pathological connection and clinical application of the three dimensions of heart yang, heart blood, and heart spirit with the life and mental activities dominated by it, as well as the overall external performance. In addition, by exploring the relationship between " heart governing the exterior" and " brain-heart axis" , " brain-skin axis" in Western medicine, it indirectly confirms the rationality of " heart governing the exterior" in Western medicine, and lays the foundation for the further development and application of the theory of " heart governing the exterior" .

Objective To understand the timeliness of antiretroviral therapy (ART) in newly reported HIV/AIDS cases in Yichang from 2016 to 2022 and its influencing factors, and to provide a scientific basis for improving the timeliness of ART in Yichang City. Methods HIV/AIDS cases data from January 1, 2016 to December 31, 2022 were collected, and chi-square tests and logistic regression were used to analyze the factors influencing the timeliness of ART. Results A total of 1 126 HIV/AIDS cases were collected, with local reported cases accounting for 83.13%. The male to female ratio was 5.15:1. The median age was 42 years old (28-53 years old). 41.03% of the cases were unmarried. 38.99% of cases had a first-time CD4+T lymphocytes (CD4 cells) count < 200 cells/µL. Cases with timely first CD4 cell test accounted for 67.85%. The overall timely rate of ART from 2016 to 2022 was 57.19%, with a median time from diagnosis to initiation of ART of 20 days. There was no statistically significant difference in the trend of ART timely rate from 2016 to 2022 (P=0.251). Cases with timely first CD4 cell test were more likely to initiate ART in time (OR=3.831, 95% CI:2.454-5.981), while cases reported from other areas (OR=0.497, 95% CI:0.345-0.716) and cases with higher first CD4 cell count levels (OR_≥500=0.473, 95% CI:0.312-0.718) were less likely to initiate ART in time. Conclusion The timely rate of antiviral treatment in Yichang City needs to be further improved. High attention should be paid to cases reported from other places, cases with delayed CD4 cell testing, and cases with high CD4 cell count levels. Treatment mobilization and referral should be done well, and early detection services should be provided in time.

Objective:To explore the pathogenicity and genotype-phenotype correlation of a c. 158G>A variant of phenylalanine hydroxylase ( PAH) gene among patients with PAH deficiency. Methods:Thirty seven children diagnosed with PAH deficiency at the Obstetrics and Gynecology Hospital Affiliated to Nanjing Medical University between July 2016 and June 2021 were selected as the study subjects. Clinical data and results of genetic testing were retrospectively analyzed.Results:Among the 37 patients, mild hyperphenylalaninemia (HPA) was observed in 34 cases, two PAH variants (including c. 158G>A), which formed a compound heterozygous mutation genotype, were detected in 33 patients, and the remainder one was found to harbor three PAH variants, including homozygous c. 158G>A variants and a heterozygous c. 842+ 2T>A variant. Classical phenylketonuria (PKU) was observed in 3 patients, and three PAH variants were detected in each of them, including two with c. [158G>A, 842+ 2T>A]/c.728G>A and c. [158G>A, 842+ 2T>A]/c.611A>G, respectively, and one with c. [158G>A, c. 722G>A]/c.728G>A. The c. 158G>A variant has a minimal influence on the PAH activity and is associated with a mild HPA phenotype. The variant should thereby be classified as likely benign. Conclusion:When the c. 158G>A variant and other pathogenic variants are arranged in cis position, the ultimate phenotype will be determined by the pathogenicity of other variants.

BACKGROUND: The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis. METHODS: In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis. RESULTS: A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP. CONCLUSIONS Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

It is discovered that activated caspase-3 tends to induce apoptosis in gasdermin E (GSDME)-deficient cells, but pyroptosis in GSDME-sufficient cells. The high GSDME expression and apoptosis resistance of pancreatic ductal adenocarcinoma (PDAC) cells shed light on another attractive strategy for PDAC treatment by promoting pyroptosis. Here we report a hGLuc-hGSDME-PCA system for high-throughput screening of potential GSDME activators against PDAC. This screening system neatly quantifies the oligomerization of GSDME-N to characterize whether pyroptosis occurs under the stimulation of chemotherapy drugs. Based on this system, ponatinib and perifosine are screened out from the FDA-approved anti-cancer drug library containing 106 compounds. Concretely, they exhibit the most potent luminescent activity and cause drastic pyroptosis in PDAC cells. Further, we demonstrate that perifosine suppresses pancreatic cancer by promoting pyroptosis via caspase-3/GSDME pathway both in vitro and in vivo. Collectively, this study reveals the great significance of hGLuc-hGSDME-PCA in identifying compounds triggering GSDME-dependent pyroptosis and developing promising therapeutic agents for PDAC.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective:To explore the relationship between gene polymorphisms of integral protein alpha-4 ( ITGA4) and intercellular adhesion molecule-1 ( ICAM-1) and the risk of ulcerative colitis (UC), and to analyze the effects of ITGA4 and ICAM-1 gene variations on the clinical response of vedolizumab (VDZ) treatment in UC patients at week-14. Methods:From January 1, 2010 to January 31, 2023, at Department of Gastroenterology of the Second Affiliated Hospital of Wenzhou Medical University, a total of 500 UC patients (UC group) and 529 gender- and age-matched healthy controls (healthy control group) were collected. The 500 UC patients were divided into mildly active stage (264 cases) and moderately to severely active stage (236 cases); distal colitis (299 cases), extensive colitis (201 cases); of the 500 UC patients, 120 cases received VDZ treatment, and 78 cases achieved clinical response and the remaining 42 cases had no response at week-14. Chi-square test and unconditional logistic regressionmodel were used to analyze the difference in gene polymorphisms of ITGA4 rs6740847, rs7562325 and ICAM-1 rs5498 gene polymorphisms between UC group and healthy control group, between patients of mildly active stage and patients of moderately to severely active stage, between patients with distal colitis and patients with extensive colitis, between patients with clinical response and patients without response through dominant, recessive, and allelic gene models. Results:The results of dominant gene model analysis showed that, the frequency of the variant allele G and the variant genotype AG+ GG of ITGA4 rs6740847 of UC group were lower than those of healthy control group (28.60% vs. 33.18%, 48.00%vs. 56.15%), the frequency of variant allele T and variant genotype CT+ TT of ITGA4 rs7562325 of UC group were higher than those of healthy control group (37.30% vs.31.57%, 62.20% vs. 54.63%), and the differences were statistically significant( χ2=5.04, 6.83, 7.49 and 6.06, P=0.025, 0.009, 0.006 and 0.014); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847 of patients with moderate to severe active UC were lower than those of patients with mild active UC (25.42% vs. 31.44%, 43.22% vs. 52.27%), while the frequency of variant allele T and variant genotype CT+ TT of ITGA4 rs7562325 were both higher than those of mild active UC (40.89% vs. 34.09%, 66.95% vs. 57.96%), and the differences were statistically significant( χ2=4.42, 4.09, 4.93 and 4.29, P=0.036, 0.043, 0.026 and 0.038); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847, the variant allele T of ITGA4 rs7562325, and the variant allele G and variant genotype AG+ GG of ICAM-1 rs5498 of patients with extensive colitis UC were lower than those of patients with distal colitis UC (24.38% vs. 31.44%, 39.80% vs. 53.51%, 33.58% vs.39.80%, 19.65% vs.26.09%, 35.82% vs. 45.82%), and the differences were statistically significant( χ2=5.87, 9.05, 3.97, 5.54 and 4.94, P=0.015, 0.003, 0.046, 0.019 and 0.026); the frequency of variant allele G and variant genotype AG+ GG of ITGA4 rs6740847 of patients with clinical response were higher than those of patients without response (34.62% vs.21.43%, 61.54% vs. 33.33%), and the differences were statistically significant( χ2=4.52 and 8.70, P=0.039 and 0.001). The results of recessive gene model analysis showed that, the frequency of variant genotype TT of ITGA4 rs7562325 of UC group was higher than that of healthy control group (12.40% vs.8.51%), and the difference was statistically significant ( χ2=4.18, P=0.041); the frequency of variant allele G and variant genotype GG of ICAM-1 rs5498 of patients with moderate to severe active UC were higher than those of patients with mild active UC (27.33% vs. 20.08%, 8.47% vs. 2.27%), and the differences were statistically significant( χ2=7.30 and 9.72, P=0.007 and 0.002); the frequency of variant allele T and variant genotype TT of ITGA4 rs7562325 of patients with clinical response were lower than those of patients without response (32.05% vs. 45.24%, 10.26% vs. 23.81%), and the differences were statistically significant( χ2=4.09 and 3.93, P=0.043 and 0.047). Conclusions:The variation of ITGA4 rs6740847 gene may reduce the risk and disease activity of UC, and may increase the clinical response to VDZ treatment in UC patients. However, the variation of ITGA4 rs7562325 gene may increase the risk and disease activity of UC, and may reduce the clinical response to VDZ treatment in UC patients. The variation of ICAM-1 rs5498 gene may worsen the disease activity of UC. In addition, the variations of ITGA4 rs6740847, rs7562325 and ICAM-1 rs5498 gene may all reduce the risk of extensive colitis.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

OBJECTIVE: To analyze the clinical features and genetic variants in four neonates with very long chain acyl-coenzyme A dehydrogenase (VLCAD) deficiency. METHODS: Neonates with a tetradecenoylcarnitine (C14:1) concentration at above 0.4 μmol/L in newborn screening were recalled for re-testing. Four neonates were diagnosed with VLCAD deficiency by MS-MS and genetic testing, and their clinical features and genotypes were analyzed. RESULTS: All cases had elevated blood C14:1, and the values of first recalls were all lower than the initial test. In 2 cases, the C14:1 had dropped to the normal range. 1 case has remained at above 1 μmol/L after the reduction, and the remainder one case was slightly decreased. In total eight variants of the ADACVL genes were detected among the four neonates, which included 5 missense variants and 3 novel variants (p.Met344Val, p.Ala416Val, c.1077+6T>A). No neonate showed salient clinical manifestations. CONCLUSION Above findings have enriched the spectrum of ADACVL gene mutations and provided a valuable reference for the screening and diagnosis of VLCAD deficiency.

Objective:To study the dynamic changes of cellular immune function in peripheral blood of trauma patients and its role in the evaluation of traumatic complications.Methods:A prospective cohort study design was conducted. Patients with blunt trauma admitted to Chongqing Emergency Medical Center from November 2019 to January 2020 were consecutively enrolled. The peripheral blood samples were collected at 1, 3, 5, 7, and 14 days after injury. The expressions of CD64, CD274, and CD279 on the surface of neutrophils, lymphocytes, and monocytes as well as CD3 +, CD4 + and CD8 + T lymphocyte subsets were measured by flow cytometry. The trauma patients were divided into different groups according to the injury severity score (ISS) and sepsis within 28 days after injury, respectively. The dynamic changes of cellular immune function in different time points after injury and differences between different groups were compared. Furthermore, the correlation with acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA), and ISS were evaluated by Pearson correlation analysis. Results:A total of 42 patients with trauma were finally enrolled, containing 8 severe trauma patients with ISS greater than 25 scores, 17 patients with ISS between 16 and 25 scores, and 17 patients with ISS less than 16 scores. The sepsis morbidity rates were 14.3% (n = 6) within 28 days after injury. CD64 index and CD4 +T lymphocyte subsets were significantly increased at different time points after trauma (H = 15.464, P = 0.004; F = 2.491, P = 0.035). The CD64 index and positive rates of CD279 in neutrophils, lymphocytes, and monocytes were increased with the severity of injury at day 1 and day 3 after injury, respectively. At the first day after injury, CD64 index were 2.81±1.79, 1.77±0.92, 3.49±1.09; positive rate of CD279 in neutrophils were 1.40% (0.32%, 2.04%), 0.95% (0.44%, 2.70%), 12.73% (3.00%, 25.20%); positive rate of CD279 in lymphocytes were 3.77% (3.04%, 5.15%), 4.71% (4.08%, 6.32%), 8.01% (4.59%, 11.59%); positive rate of CD279 in monocytes were 0.57% (0.24%, 1.09%), 0.85% (0.22%, 1.25%), 6.74% (2.61%, 18.94%) from mild to severe injury groups, respectively. The CD64 index in severe injury group was significantly higher than that in moderate group, and the positive rates of CD279 in neutrophils, lymphocytes and monocytes of severe injury patients were higher than those in other two groups (all P < 0.05). At 3rd day after injury, compared to moderate group, severe injury patients had significantly higher CD64 index and positive rate of CD279 in lymphocytes [4.58±2.41 vs. 2.43±1.68, 7.35% (5.90%, 12.28%) vs. 4.63% (3.26%, 6.06%), both P < 0.05]. Compared with the non-sepsis patients, the sepsis patients had significantly higher CD64 index and positive rate of CD279 in monocytes at day 1 after injury [4.06±1.72 vs. 2.36±1.31, 3.29% (1.14%, 12.84%) vs. 0.67% (0.25%, 1.48%), both P < 0.05], and positive rate of CD279 in lymphocytes significantly higher at 3rd day after injury [8.73% (7.52%, 15.82%) vs. 4.67% (3.82%, 6.21%), P < 0.05]. In addition, correlation analysis showed that positive rate of CD279 in lymphocytes was positively correlated with SOFA and ISS, respectively (r values were 0.533 and 0.394, both P < 0.05), positive rate of CD279 in monocytes was positively correlated with APACHEⅡ, SOFA and ISS scores, respectively (r values were 0.579, 0.452 and 0.490, all P < 0.01), positive rate of CD279 in neutrophils was positively correlated with APACHEⅡ and ISS, respectively (r values were 0.358 and 0.388, both P < 0.05). Conclusions:CD64 index and CD279 expression in neutrophils, lymphocytes, and monocytes are significantly related to the severity and prognosis of trauma. Dynamic monitoring the cellular immune function may be helpful for assessing the prognosis of trauma patients.
